Grapevine plant named ‘Sugarfortyseven’

ABSTRACT

A new and distinct grapevine variety ‘Sugrafortyseven’ is characterized by an early harvest date, the production of a large-sized, red, globose berry and a large bunch size. The berries of ‘Sugrafortyseven’ are very firm. The new variety ‘Sugrafortyseven’ is characterized by a higher cluster weight and berry weight compared to ‘Flame Seedless’ (unpatented). The new variety has similar berry color to the variety ‘Crimson Seedless’ (unpatented) but begins ripening earlier.

Latin name of the genus and species claimed: Vitis vinifera.

Variety denomination: ‘SUGRAFORTYSEVEN’.

BACKGROUND AND SUMMARY OF THE INVENTION

This invention relates to the discovery and asexual propagation of a new and distinct variety of grapevine, ‘Sugrafortyseven’, as herein described and illustrated. The new variety was first selected as breeder number ‘GR305R’ by Terry A. Bacon in Wasco, Kern County, Calif. in July 2012. The variety was originated by controlled hybridization.

The new variety ‘Sugrafortyseven’ is characterized by an early harvest date, the production of a large-sized, red, globose berries, and a large bunch size. The berries of ‘Sugrafortyseven’ are very firm with a crisp texture.

The seed parent is the varietal selection ‘Sugrathirtyeight’ (U.S. Plant Pat. No. 22,431) and the pollen parent is an unpatented breeding selection (‘02031-176-252’). The parent varieties were first crossed in May 2010. The date of first sowing was March 2011, and the date of first flowering was May 2012.

The new variety ‘Sugrafortyseven’ was first asexually propagated in December 2012 in Wasco, Kern County, Calif., by Terry A. Bacon using hardwood cuttings.

The new variety ‘Sugrafortyseven’ is similar to its seed parent ‘Sugrathirtyeight’ (U.S. Plant Pat. No. 22,431) in that both varieties have a similar berry color, but they differ in that the new variety ‘Sugrafortyseven’ has a ripening time of about July 9^(th) compared to August 3^(rd) for ‘Sugrathirtyeight’ (U.S. Plant Pat. No. 22,431).

The new variety ‘Sugrafortyseven’ is similar to its pollen parent, unpatented breeding selection ‘02031-176-252’, in that both varieties have a similar ripening time. The new variety differs from its pollen parent in that the new variety ‘Sugrafortyseven’ has a berry that is red in color while ‘02031-176-252’ has a green berry.

The berry color of the new variety ‘Sugrafortyseven’ resembles the variety ‘Flame Seedless’ (unpatented) in appearance. However, the cluster weight of the new variety is about 700 g and berry weight is about 7.8 g, while the cluster weight of ‘Flame Seedless’ is about 550 g and berry weight is about 5 g. The new variety has similar berry color as the variety ‘Crimson Seedless’ (unpatented). However, the new variety begins ripening around July 9th, compared to August 28th for ‘Crimson Seedless’. The new variety ripens in a similar window as the variety ‘Summer Royal’ (unpatented), and the two varieties have a similar berry shape. However, the berry of ‘Summer Royal’ is black while the berry color of the new variety ‘Sugrafortyseven’ is red.

The new ‘Sugrafortyseven’ variety has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, cuttings and grafting.

Variations of the usual magnitude from the characteristics described herein may occur with changes in any of a variety of factors such as growing conditions, irrigation, fertilization, pruning, management and climatic variation.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new grape variety ‘Sugrafortyseven’.

The illustration shows the upper and lower surface of the leaves and exterior and sectional views of the fruit.

The photographic illustration was taken shortly after the fruit was picked and the colors are as nearly true as is reasonably possible in a color representation of this type.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon The R.H.S. Colour Chart, published by The Royal Horticultural Society, London, England, 1986.

Many of the descriptive values in this specification are based on and conform to those set forth by the International Board for Plant Genetic Resources Institute Grape Descriptors (Vitis spp.) of 1983 and/or 1997, which was developed in collaboration with the Office International de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties of Plants (UPOV).

The descriptive matter which follows pertains to ‘Sugrafortyseven’ plants grown in the vicinity of Wasco, Kern County, Calif. during 2015, and is believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere.
